I have temperature as a raster file and different ZIP Code Tabulation Areas (ZCTAs) as polygons. I'd like to calculate the mean temperature per zip code.
I need to know the temperature value per ZIP code region and I am trying to use the zonal statistics as table but my results are showing only one row out of 1769 ZIP codes. What could be the reason why this is happening? I also tried to do zonal statistics and wasn't successful either.
I thought that maybe the problem was that the raster (TIFF) is not only for California and my shapefile is of CA. I don't know if that's relevant.
